Hi,

I need to know more how PXC Scheduler works in clustered ProxySQL environment. What will be happen if the lock holder ProxySQL node is down? How it failover the scheduler to one of available ProxySQL nodes? When I enable PXC Scheduler in clustered ProxySQL environment, I can see that only lock holder ProxySQL node has scheduler configuration inside.

Best regards.

Hello @Mrxlazuardin,  
Can you give some more background here? Is this K8S, or standalone? What is the ‘PXC Scheduler’, do you have a link?
